  • Moderate evidence4 studies

    Across 4 studies, 3 report beneficial effects of vitamin D supplementation on reducing parathyroid hormone (PTH) levels, with small-to-moderate effect sizes (e.g., MD -4.19 pg/mL, SMD -0.49). Evidence primarily comes from systematic reviews and meta-analyses in clinical populations (depression patients, kidney transplant recipients, healthy adults). A neutral study in bariatric surgery patients found no significant difference between high and moderate doses. The median study duration was 90 days, suggesting effects may require several weeks to emerge.
